Converting measurements is a key fifth-grade math skill that students use to solve problems across the customary and metric systems. Fifth graders convert customary units of length (inches, feet, yards), weight (ounces, pounds, tons), and capacity (cups, pints, quarts, gallons), and metric units of length (millimeters, centimeters, meters, kilometers), mass (grams, kilograms), and volume (milliliters, liters).
The main challenge is that students multiply when they should divide or divide when they should multiply — converting 3 feet to inches by dividing 3 by 12 instead of multiplying. Students also confuse metric and customary relationships, treating 1 liter as 100 milliliters rather than 1,000. In Grade 4, students converted within a single measurement system; Grade 5 extends to multi-step conversions and mixed-unit expressions.
Our converting measurements worksheets give fifth graders structured practice correcting unit-conversion errors, applying customary and metric conversion facts, converting mixed-unit measurements, matching equivalent measures, and solving multi-step word problems that require converting within and across measurement categories.

Common Mistakes to Watch For
- Dividing instead of multiplying when converting to smaller units — students compute 3 feet = 3 ÷ 12 = 0.25 inches instead of 3 × 12 = 36 inches. Converting to a smaller unit always requires multiplying by the conversion factor. Converting to a larger unit requires dividing.
- Using the wrong conversion factor for metric units — students write 3 liters = 300 milliliters instead of 3,000 milliliters, confusing the metric factor of 1,000 with 100. Metric conversions between adjacent units always use a factor of 10, 100, or 1,000 depending on the unit pair.
- Misremembering customary capacity relationships — students write 1 gallon = 8 quarts instead of 4 quarts, or confuse pints and cups. The customary capacity chain is 2 cups = 1 pint, 2 pints = 1 quart, and 4 quarts = 1 gallon — each step doubles, not triples or quadruples.
Frequently Asked Questions
How do I know whether to multiply or divide when converting units?
Ask: am I converting to a smaller unit or a larger unit? Converting to a smaller unit means more of them are needed — multiply by the conversion factor. Converting to a larger unit means fewer are needed — divide by the conversion factor. For example: 5 feet to inches is converting to a smaller unit, so multiply: 5 × 12 = 60 inches. Going from 48 inches to feet is converting to a larger unit, so divide: 48 ÷ 12 = 4 feet. A unit fraction can also help: multiply by the fraction that cancels the starting unit.
What are the most important customary length and weight conversion facts?
For length: 12 inches = 1 foot, 3 feet = 1 yard, 5,280 feet = 1 mile, 1,760 yards = 1 mile. For weight: 16 ounces = 1 pound, 2,000 pounds = 1 ton. These facts must be memorized. For a multi-step conversion like yards to inches, chain the facts: 1 yard = 3 feet and 1 foot = 12 inches, so 1 yard = 36 inches. When converting mixed measurements like 2 feet 5 inches, first convert 2 feet to 24 inches, then add 5 to get 29 inches total.
What are the key customary capacity conversion facts?
The capacity chain is: 2 cups = 1 pint, 2 pints = 1 quart, and 4 quarts = 1 gallon. From cups to gallons: 16 cups = 1 gallon. From pints to gallons: 8 pints = 1 gallon. A helpful way to remember: each step going up the chain doubles — 2 cups make a pint, 2 pints make a quart. To convert 3 quarts to pints, multiply: 3 × 2 = 6 pints. To convert 6 cups to pints, divide: 6 ÷ 2 = 3 pints.
How do metric unit conversions work?
Metric units are based on powers of 10, making conversions straightforward. For length: 10 millimeters = 1 centimeter, 100 centimeters = 1 meter, 1,000 meters = 1 kilometer. For mass: 1,000 grams = 1 kilogram. For volume: 1,000 milliliters = 1 liter. To convert a larger unit to a smaller unit, multiply by 10, 100, or 1,000. To convert a smaller unit to a larger unit, divide. For example: 3.5 kilometers = 3.5 × 1,000 = 3,500 meters. And 250 centimeters = 250 ÷ 100 = 2.5 meters.
How do I solve a multi-step measurement word problem?
Read carefully to identify all the units and what the question asks. Convert all measurements to the same unit before adding, subtracting, or comparing. For a carpenter with an 8-foot board who cuts off 30 inches: first convert 8 feet to 96 inches, then subtract 30 inches to get 66 inches remaining. Check whether the answer should be in the original unit or the converted unit. Write your conversion steps clearly and label units at each step — missing or mismatched units are the most common source of errors in multi-step measurement problems.
